Netcraft Hosting Provider Performance Monitoring

Netcraft measures and makes available the response times of leading hosting providers' sites. The performance measurements are made at fifteen minute intervals from separate points around the internet, and averages are calculated over the immediately preceding 24 hour period.

Note: Outage times display the minimum outage time which may
understate each outage by up to 15 minutes, which is the sampling
frequency.

Interpreting the Tables

By default the sites are ranked in order of failed requests and time to
connect, shortest first, in order to give the clearest indication of network
capacity and congestion, with the least impact from the performance of the
individual web server, though it is possible to sort by other columns by
clicking on the column heading.

Presently our performance collectors are located at
London/DXI Networks, San Jose/Datapipe, Phoenix/GoDaddy, Zurich/Qube, Amsterdam/Webair, New York/New York Internet-2, Italy/Aruba-2 and Pennsylvania/INetU-3.
Sites located near one of our collectors may have an advantage over others
listed in the table, though this effect is mitigated by using averages
collected from multiple points. Sites exclusively hosted in the Far East are
at a disadvantage as we do not currently have a performance collector in the
region.

Sites using a Content Distribution Network, such as Akamai, have a particular
advantage as the response to our request would come from the node closest to
each performance collector.

Using the performance of a hosting provider's own site to determine the
performance of the hosting companies network, is only indicative.

If you are using the table as a guide when choosing where to locate a
dedicated or collocated server, remember that connection times fluctuate
continually, and only hundredths of a second separate the top companies.
Avoiding companies showing prolonged outages is likely to be a better
strategy than necessarily going for the company with the fastest
connection time.

Other factors including availability and quality of support, and price
will also be important. If you are considering shared hosting then the
load on the shared hosting system will likely be a greater constraint on
the performance of your site than network connection time.
